Answer:
number of Al atom =54÷27=2atom of Al. number of o atom = 160÷16=10 atom of o . =214U MASS of ALO2.
Balanced Equation is
4H2SiCl2+4H2O → H8Si4O4 + 8HCl
The list of options to answer this question is:
A.kinectic energy is transformed into thermal energy.
B.electrical energy is transformed into potential energy.
C.potential energy is transformed into kinectic energy.
D.mechanical energy is transformed into chemical energy.
The answer is the option A. A.kinectic energy is transformed into thermal energy.
As you know energy cannot be lost but transformed.
When friction force acts over the tyres it increases the speed of the particles in the tyres which is thermal energy, this thermal energy increase comes from kinetic energy loss.
The total pressure is given by:
P = ∑xiPi
P = 1/2 x 81 + 1/2 x 45
P = 63 kPa
